Unique Methodological Issues Facing Randomized Controlled Trials of Endourologic Procedures
Bibliographic record
Abstract
Randomized controlled trials provide the optimal design for evaluating the effectiveness of treatment but have not been widely accepted by surgical investigators. Although there are several methodological and ethical difficulties, none is insurmountable. In the United Kingdom, a regulatory agency has been established to supervise the introduction of new medical procedures, and something similar might be seen in the United States, particularly given the pressure from the government and third-party payors for proof of efficacy and cost effectiveness. Endourologists have responded to similar challenges in the past and must continue to do so.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; the direct Gemma label and the distilled Codex classifier agree on what is shown here.
